Homework Statement
A simple camera has a converging lens of focal length 50.0 mm.
It is used to photograph a tree 3.00 m high.
The tree is 8.00 m away from the lens.
Calculate the distance v between the lens and the film, giving your answer in mm to three significant figures.
Homework Equations
1/f = 1/u + 1/v
The Attempt at a Solution
1/50 = 1/8000 + 1/(-v)
v = -50.3 mm
Is this correct? Thank you!
